I have on an X1300 on a pci-e slot a similar / identical issue. I see the following repeating block in Xorg.0.log:
Received Interrupt event message: ... dwIRQSource: 20008000 ... dwIRQCounter: 5 ... dwIRQEnableId: 0000000000000008 ... pvKernelEvent: (nil) ... pvEventHandle: (nil) ... dwContextData: 00000000 ... ullStartTime: 3578707608l ... ullEndTime: 582l Received Interrupt event message: ... dwIRQSource: 20008000 ... dwIRQCounter: 6 ... dwIRQEnableId: 0000000000000008 ... pvKernelEvent: (nil) ... pvEventHandle: (nil) ... dwContextData: 00000000 ... ullStartTime: 4131610152l ... ullEndTime: 2110022l Each time this message appears I notice a short lock of the screen and a cpu peak. this message repeats itselfs very often. The cpu peak is only if atieventsd is running. -- [fglrx] Using fglrx causes excessive hardware interrupts and an extremely slow system https://bugs.launchpad.net/bugs/206337 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
